Lemon & Salt Battery

A Lemon & Salt Battery is a simple electrochemical cell that demonstrates how acidic solutions can generate electricity. It consists of a lemon infused with salt, along with two different metal electrodes—typically a zinc (anode) and a copper (cathode). The lemon's acidic juice acts as an electrolyte, allowing ions to move between the electrodes, generating a small electric current. This battery can power low-energy devices like LED lights or digital clocks, making it a popular educational experiment to explain basic concepts of electricity and chemical reactions.
